Got a 00 trans am. Alternator went bad on me at 115k. Ordered a new one online and installed and still not charging. I guess it is possible to have a bad new alternator.. I know it is easy to break the exciter wire since it is difficult getting the alterator out but it dont look broke. is there a way to test this before pulling the alt back out and returning it?

Above is correct.... or you could take a jumper wire from your posative terminal. to that post on the alternator and see if it starts charging... will probably charge really high as thats supposed to have a reisitor inline, but that would be the way to rule it out.. ..
